Member Function Documentation

◆ debug_level()

debug_level_type hoayy::parser::debug_level ( ) const

The current debugging level.

◆ debug_stream()

std::ostream & hoayy::parser::debug_stream ( ) const

The current debugging stream.

◆ error() [1/2]

virtual void hoayy::parser::error	(	const location_type &	loc,
		const std::string &	msg
	)

virtual

Report a syntax error.

Parameters

loc	where the syntax error is found.
msg	a description of the syntax error.

◆ error() [2/2]

void hoayy::parser::error ( const syntax_error & err )

Report a syntax error.

◆ operator()()

int hoayy::parser::operator() ( )

Parse. An alias for parse ().

Returns: 0 iff parsing succeeded.

◆ parse()

virtual int hoayy::parser::parse ( )

virtual

Parse.

Returns: 0 iff parsing succeeded.

◆ set_debug_level()

void hoayy::parser::set_debug_level ( debug_level_type l )

Set the current debugging level.

◆ set_debug_stream()

void hoayy::parser::set_debug_stream ( std::ostream & )

Set the current debugging stream.

◆ symbol_name()

static std::string hoayy::parser::symbol_name ( symbol_kind_type yysymbol )

static
